Blockchain was first introduced in October 2008 through the white paper released by Satoshi Nakamoto describing how a virtual currency (Bitcoin) could potentially work. Blockchain by design is a decentralized technology, where information held on its network reconciled to the database regularly. The blockchain database isn’t stored in any single location instead, it is spread across nodes on the blockchain network. Similar to a peer to peer network, transactions are broadcast, database hosted by a network of computers accessible to the public with no centralized storage, making it impossible for hackers to manipulate. Blockchain technology is unique in the way that it brings together existing technology of peer to peer network, cryptography, along with game theory (providing rewards through competition) to establish a secure medium where functions can take place without a centralized entity.
